Claims.

This invention relates in general to an electric controller for a plurality of circuits which may be independently energized to perform an electrical function at a distance from the device, and it is more particularly described as a controller for remotely controlling a phonograph mechanism after the insertion of coins of various sizes.

An important object of the invention is in the provision of means for receiving one or more coins and after the coins are inserted, for selecting one or more of the electrical circuits corresponding to designated phonograph selections on the face of the controller, so that after a predetermined number of selections has been made the mechanism is automatically restored to its inoperative state.

In carrying out the invention the controller also includes various means to prevent fraudulent operation without the insertion of coins, and other means to prevent the operator from obtaining or playing selections in excess of those called for by the insertion of the proper .coin, or the proper number of coins.

Other objects of the invention will appear hereinafter, the preferred construction and various modifications being illustrated in the accompanying drawings, in which Figure 1 is a front view of asuitable casing in which the operating mechanism is housed;

Figure 2 is a rear view of the mechanism enclosed in the casing;

Figure 8 is a perspective showing a pair of the push button locking latches;

Figure 9 is a wiring diagram illustrating the operation of the controller; and

Figure 10 is a sectional view illustrating a mechanical modification of the non-interference locking plate.

This remote controller is constructed so that it may be operated by the insertion of various co ns such as nickles, dimes, and quarters and is electrically connected by means of a multiple cable to any selective device such as a phonograph having electrical means for playing any one of the selected records. It is intended that any record may be selected for play for each five cent value, and a record may be repeatedor different records may be played depending upon the multiples of five-cents which are inserted.

Referring now more particularly to the drawings, the mechanism of this controller is assembled and housed in a case or cabinet I! usually of pleasing structure, design and color. At the center of th front face are two rows of push buttons I3 and H, which are adjacent to indirectly illuminated program slips l5 and [6, adjustable in frames l1 and I8 corresponding to the selections to be played by a remote phonograph. At each outer side of the frames I1 and I8 is a window l9, and these windows, as well as the program slips, are directly or indirectly illuminated by electric lamps 20 within the casing. The windows l9 may contain pertinent or other advertising matter, and the program slips are usually illuminated so that they can be read more easily.

Directly below the program plates are three conventional coin slides 2!, 22 and 23, movable through face plates 24 and adapted to receive ten-cent, five-cent, and twenty-five cent coins respectively.

The front face or wall of the cabinet is preferably of opaque material and the push buttons l3, l4 projecting forwardly therefrom (see also Figure 10), are of transparent or translucent material, each being mounted upon a stem 25 which projects through a plate 26 spaced from the front plate of the cabinet a sufiicient distance so that small electric lamps 21 may be placed therebetween. The rear end of each push button is formed with a shoulder 28 which limits its movement in a forward direction, and the rear of the shoulder portion is either painted or coated to make it opaque, or the shoulder itself is opaque so that when the push button is closed it is not illuminated, but as soon as a push button is depressed the outer portion thereof which is translucent will be illuminated by the lamps 21, thereby clearly indicating any of the buttons which are pushed inwardly.

At the upper end of the front of the sin may be a clock 29 for indicating the time as it relates to the controller, and for decoration purposes.

Also located within the casing is a transformer 3| for furnishing low voltage current to the miniature lamps 21 for illuminating the push butions; the coin receiving mechanism at the inner ends of the coin slides as shown more clearly in Figures 2, 3, and 4: the selection adding and subtracting mechanism as shown more clearly in Fleur-es 2 and ii; the push button restoring magnet 82: and a metal box a at the base of the cabinet for receiving coins inserted in the casing.

Each of the coin slides is slidable in a. guide It projecting from the face plate and having a recess II at the top for allowing the insertion of the proper coin within an opening 20, 21 or 2|, of the corresponding slide. At the bottom of each guide is an opening I! by means of which a coin inserted in the opening of the slide may be dislodged before the slide is pushed inwardly. Each slide includes conventional means for deteoting and rejecting spurious coins which forms no particular part of this invention. Mounted above and below each sliding member of the coin slide (see Figures 3 and 4), are latches Ill and I which prevent the slide from moving inwardly until the proper coin is inserted. At one side of each slide is a ratchet device 94 which prevents manual rec procation or return inward movement of the slide after it has been operatively inserted to the required extent. These safety devices are shown by Patents 1,908,308 and 1,908,752, but form no part of this invention, and are not here described in detail.

At the rear ends of the slides 2|, 22 and 23 is a locking device for insuring that only one slide may be operatively inserted at a time, thus preventing an operator from losing plays by insertins two or more slides at the same time. This locking device comprises a plate l2 mounted to move transversely of the slides by means of fastening screws 43 inserted through openings larger than the screws in the plate. and into a fixed support 44. Projectin upwardly from the plate 42 are spaced pins 45 extending through slots I in the support it beyond the upper side thereof. and into the path of the ends of the slides 2|, 22 and 22. The extremities of these slides are cut off angularly at the corners to provide angular shoulders ll adapted to engage the projecting pins II for moving the locking plate 42 accordingly. By reference to Figure 3, it will be seen that the locking pins 45 for the central slide 22 are spaced apart exactly the proper distance to allow this slide to pass between the central pins 45, but in this position if the slide 22 is inserted between them the two outer pins 45 will be locked in the paths of the outer slides 2| and 23 engaging the shoulders 41 thereof, and preventing their inward movement. Likewise, if either one of the outer slides is pushed inwardly its shoulder 41 will engage the corresponding outer pin 45, pressing the locking plate 42 lengthwise and locating other pins directly in the paths of the other slides, thereby preventing their operation.

In operating the slides the five-cent slide produces a single operation or makes provision for playing a single selection, the ten-cent slide two selections, and the twenty-live cent slide five selections. The mechanism operated by the slides is shown more clearly in Figures 3 and 4, and

comprises a rotatable shaft 50 positioned above 1 the slides 2|, 22 and 22, and mounted in suitable bearings at the ends. Secured to the shaft by a set screw is an arm Si in the path of a latch 52, carried by the ten-cent slide 2i; and an arm 53 similarly secured to the shaft in the path of a latch 54 carried at the rear of the five-cent slide 22. A gear 55 is secured to the shaft opposite a latch 5,8 or the twenty-five cent slide 23, but this latch engages a slide 51 having a, rack II in engagement with the gear II and mounted by means of a slot II and bearing screws II which are inserted in an upstanding support Ii so that when engaged by the latch II the gear II and the shaft II will be rotated an amount equal to five steps or the movement of the shaft.

Each of the latches 2, II and I. is mounted upon a pivot 22 at one and between spaced upright supports '8 carried by its slide and has a pin or projection N at the other or free end. Each latch is held releasably in either one of two positions by means of recesses or openings II and it in the latch engaged by a ball 21 seated in an opening therefor in one of the supports I, and held in this opening by a spring ll attached at one end to the support and bearing at the other upon the detent ball.

In its raised position with the ball engaging the lower recess 66 each latch will engage its corresponding arm Ii, I3 or the slide ll during the rearward movement of its slide. When each latch is engaged by the detent ball in the upper recess 85, each latch will be held out of contacting position with respect to its corresponding arm or slide 51. 4

In order to move each latch from one position to another two guides 10 of similar shape are secured to the support 4| over the rear paths of movement of the coin slides and each of these guides comprises an angular hook H at the rear end located in the path of one or more of the latch projections 64, a depressed intermediate portion and a raised front portion I2 connected to the intermediate part by an inclined portion ll such that as a coin slide is moved inwardly its latch 58 will engage and move its slide ill and near the rear end of its travel will engage the tripping hook H which will pull the latch it downwardly, disengaging the ball detent from the lower latch recess 86 and engaging the upper latch recess 85, thereby preventing the coin slide from being operatively reciprocated back and forth near the end of its stroke, but allowing it to be moved forwardly, and preventing it from engaging one of the corresponding arms II or I by such movement because the latch is too low at that time, and only restoring the latch to its operating position when the projection 64 thereof engages the inclined portion ll of the guide, upon its forward return movement, thereby re-engaging the ball detent with the lower latch recess 66 and placing the latch in position for the next operation.

At one end of the operating shaft 50 is an ordinary telephone contact dial mechanism II for making and timing the necessary contacts made by the coin slide latches. This mechanism comprises a spring 16 at the end of the shaft for returning the shaft and the rack plate 58 to its normal position for reoperation by the coin slides. It also includes a gearing and a governor for retarding the gearing (not shown), and rotating a double ended cam contact maker 11 for closing a switch 18 (see Figure 9), in accordance with the actuation of the shaft 50 by the coin slides. In the case of the five-cent coin slide the shaft 50 is rotated sufficiently so that one contact of the switch It is made, the ten-cent slide produces rotation suflicient for two contacts, and the twenty-five-cent slide produces sufficient rotation to make five contacts. The timing or retarding of the returning movement is for the purpose of insuring that these operations of the switch 18 will not be too rapid.

Through an electrical circuit closed by the telephone dial switch 18, the adding and subtracting mechanism for playing any number of records, depending upon the denominations of the coins, is brought into operation. This mechanism is shown in position in the casing in Figure 3, and in its diagrammatic relation to the other parts in Figure 9. It comprises a magnet 88 periodically energized by the timed closing of the contacts of the telephone. dial switch, thus actuating its armature 8| which includes an escapement pawl for an escape wheel 82 actuated by a spring 88 and the pawl being held normally so that the armature is spaced from the magnet by a spring 88. At one side of the escape wheel are electrical contact fingers 85 and 85 normally held in spaced apart relation by a contact pin 81 carried by the escape wheel. As soon as the magnet 88 receives its first impulse the toothed wheel 82 is moved one step and the pin 81 allows the contacts 85 and 85 to close.

The escape wheel 82 is thus rotated a number of steps corresponding to the coins which have been inserted and an operator may choose the remote control selections which he desires played corresponding to this number of steps by operating the push buttons. For each push button that is operated, the subtracting mechanism will rotate the escape wheel 82 in a reverse direction. by means of a magnet 88 which has an armature with an extension 88 provided with a tooth 88 for engaging the teeth of the escape wheel and having a slot 8i controlled by a projection or screw 82 inserted therethrough, the armature and extension being drawn outwardly by a spring 88 to such a point that the tooth 88 is out or engagement with the wheel 88, thereby allowing the wheel to be rotated by its spring 88 whenever t e escapement pawl is operated by the magnet 88. When the magnet 88 is energized its armature and the extension 88 are drawn inwardly and in the return movement caused by the spring 88 the tooth 88 engages one of the teeth of the spring wheel 82, caus ng a reverse or subtracting movement of the wheel against its spring 88, tending to return the projection 81 to separate the contact fingers 85 and 88. As soon as these contacts are separated there can be no more playing of records until more coins are inserted by the coin slides. The magnet 88 is energized when any one of the push buttons is operated for choosing any of the selections as hereafter explained.

Any desired number of selector buttons I8 or I8 may be employed. This controller shows two rows of ten buttons, each operative to produce a corresponding operation and each row or set having an electrical or a mechanical means for preventing more than one play at a time.

Each push button stem 25 is mounted to slide through fixed plates 28 and 85, spaced apart and located at the rear of the face plate. Intermediate the ends of the stem is a notch 85 so located that when a push button is depressed the notched portion is pressed through the plate 85 where it may be engaged by a latch 81 having a perforation 88 slightly larger than the stem through which the latter extends. n the stem between the plates 88 and 85 is a groove 88 in which a spring collar I88 is seated to form a stop for one end of a button returning spring I8I the spring being mounted at the other end upon a sleeve I82 having an enlarged shoulder I88 which abuts the face of the plate 85. Thus, when any button is pressed inwardly the spring I8I is compressed about the sleeve I82.

The rear end of each stem 25 extends through an insulated back plate I88 upon which are mounted spring contacts I and I88 at opposite sides of each stem, and a single contact I81 at one side of the stem at right angles to the other two contacts.

Between the plates 85 and I88 a spring collar I88 is also attached to each stem 25 forming a stop for a contact maker I88 mounted upon an insulating sleeve H8 and slidable upon the stem under the influence of a spring III surrounding the stem and disposed between the sleeve I I8 and the insulated plate I88. This contact maker is preferably of metal adapted to make electrical connection between the bent tips of the conductors I85 and I88 on opposite sides of the stem or between the conductors I85 and I81 when the push buttons are pressed inwardly. When the push buttons are in their outermost position, the contact makers I88 make a series connection between all of the spring contacts I85 and I85 of adjacent push buttons and when a push button is depressed through its entire range, the contactor I88 makes a connection between the spring finger I85 at one side of the stem, and its conductor I81 at right angles thereto for the purpose of closing a single remote circuit connection. The spring III pressing the contact maker I88 tends to make a series connection between the contacts I85 and I85 at opposite sides of each stem except when the push button is depressed through its entire range, as shown by the upper button at the top of Figure '1.

When any button is released after depressing it through its entire range, it is engaged by its latch 81 and a connected mechanism as shown more clearly in Figures 6 and 8. There is a separate latch 81 for each push button stem 25, the latch being mounted at one end upon a pivot II2 attached to the bearing plate 85 and the other end of the latch having an extension II8 overlying a stud II8 projecting from a vertical bar II5 so that the projections of corresponding buttons of two rows engage the same stud I I8.

To operate the bar II5 a magnet H8 is attached by suitable brackets H1 at one side of a frame H8, in which the push button stems are mounted, and has an armature II8 with an attached cross bar I20 extending through the frame H8, and having a spring I2l interposed between the other side of the frame and a washer I22 at the other projecting end of the shaft I28. Connected to this cross bar is one end of an angle lever I28 having a pivot I28 for mounting it intermediate its ends upon the plate 55, and

its other end connected by a link I25 with the vertical bar H5. The action of this connection is that when the magnet I I 5 is energized, the cross bar I28 is pulled against the action of spring I2I, causing the vertical bar II5 to move downward and allowing the latches 81 to fall by gravity against the stems 25 of the push buttons. Whenever any stem is pushed sufllciently through the plate 85 so that its latch 81 can engage with the notch 88, the weight of the latch will cause it to engage in the notch, preventing the push button from being returned by its spring IN to the outermost position. This will expose the outer transparent end of the push button which will be illuminated by one of the lamps 21 indieating that this button has been depressed.

When any push button is depressed to make an operative connection with its contact I81 the series connection through the other buttons is broken, as hereinafter explained in connection with the wiring diagram, and the depression of any other button can have no efiect and only the circuit corresponding to the button which is depressed will be energized. This arrangement prevents the operator from obtaining more than one operative connection or one play at'a time.

As soon as any button is depressed the escape wheel magnet 99 is energized, bringing the tooth or its pawl 99 back into operative position with the escape wheel 92.

As soon as a. push button is permitted to return part way under the influence oi its spring IOI, and limited by its latch 91, the remote control circuit through the contact I 01 is broken and the pawl 01' the magnet 90 is returned by the action oi its spring 92, thus returning the pawl wheel one step. In this position, the series connection Is again made through the spring contacts I05, I99, so that any the other push button control circuits may be established by depressing them singly throughout its entire range.

After a number 01' plays have been selected by the push buttons corresponding to the coins inae'rted, the pawl wheel 92 will have returned to its normal position in which the contact pin 91 engages the extremity oi contact finger 95, and separates it from contact finger 96,- thereby breaking the connection to the magnet H9 and allowing the spring I2I to move the cross bar I29, thus raising the vertical bar H5 and through it, raising all of the latches 91 by the mntact of the studs H4 with the extensions II9 thereof, thereby releasing each of the push buttons from the latch engagement of the notches 99 and thereby allowing the springs I02 to return the push buttons to their normal outermost and unilluminated position.

A mechanical means of preventing more than one push button from being depressed at one time, is illustrated in Figure 10. In this form each of the push button stems I26 is slidable in front and rear plates I21 and I29, respectively. Between these plates is a slidable plate I29 having perforations I90 corresponding in number to the push button stems, but the center distances between the holes being varied. Slidably mounted upon each stem at one side or the plate III is a conical member ItI in which the smaller end of the cone is sumciently large to engage in the opening I90 of the plate I29 in any position. The larger end of the member will only pass through its opening I30 of the plate when in proper alignment and the conical member is urged into engagement with the plate by a spring III surrounding the stem I28 and bearing at one end against the larger end of the conical member and at the other end against a washer I92 fixed to the stem and normally abutting the front plate I21.

At the other side of the plate I29 is a contact maker I39 mounted upon an insulating sleeve I94 secured to the stem and pressed normally toward the plate by a spring I95 bearing at one end against the sleeve I34, and at the other end against the plate I29. Mounted upon the plate I29 at opposite sides or each stern are spring contacts I39 adapted to be engaged by the contact maker I93 whe it is sufilciently moved against its spring I".

Thus, when a single push button is depressed, the plate I29 which is slidable longitudinally, is moved by the conical portion of the cone member ISI so that the corresponding hole I20 in the plate is axially aligned, and the cone then proiects through its opening into engagement with movement of the plate I29 by the depression 0! any of the other push buttons. At this time some or the conical members will extend partially into their openings I in the plate. The actuated push button whose conical member positions the plate, extends through the hole I20 thereof, and into en agement with the contact maker I99, or its sleeve I24, pressing it against the tension of its spring I30 and into contact engagement with the spring contact fingers I 29. Thus, it will be seen that when one or the buttons is depressed, no other button can be depressed until the operated button is returned to its outer or normal position by the spring I35. As soon as the conical member oi the depressed button is moved by the spring I95, into engagement with its hole I N of the larger portion of the cone, preventing the the plate I29, any of the other push buttons may be depressed, moving the plate into alignment and preventing the operation or any other buttons in the same manner.

In applying this controller it may be assumed in connection with Figure 9 that the push buttons are for the purpose of closing operating circuits to a number oi. electro-responsive devices A-I, A- 2, A-3, A-4, A-5 and A-B, having a number of corresponding push button switches B-I, S2, 8-3, 8-4, 8-5 and 8-4, and B, each device connected to its corresponding fixed switch contact I01 by conductorsG-I, C--2, 0-9, 0-4. 0-4 and (3-9 and having a common terminal conductor I I1, excepting switch 8, the connections for which are shown broken to indicate that any further or additional switches may be provided ii necessary or desired.

At the start, all of the push buttons are in their normal or outer positions with their contact makers I09 making a series connection between the contact fingers I05 and I09 free from contact with the respective energizing fingers I 01. An operator desiring to play a number of selections deposits one or 'more coins in the slides 2|, 22 or 29, which causes a corresponding operation of the timing dial mechanism I5 to rotate the contact maker 11 for closing the switch I8 a corresponding number of times. This energizes the magnet a corresponding number of times, closing an energizing circuit from a main or source of supply as follows: from current supply main I99 through conductor I", switch 19 and conductor I40 to one end of the magnet winding 90 and thence through the winding conductor HI and a manually operated switch I42 to the other supply main I43. Each time the magnet 80 is energized it attracts its escapement pawl armature 8|, allowing the spring 89 to ro tate the escape wheel 02 one step in a clockwise direction, thereby moving the contact pin 91 away from the spring contact finger 05 and allowing the contacts 05 and 90 to close.

Closing the contacts and 06 causes an energizing circuit to be set up through the winding of magnet IIG from the supply main I30 by way of conductor I44 through the contact fingers ll, 98, conductor I45, through the magnet winding H6 and then through conductor I46 and switch I 42 to the other main I43. Energizing the magnet IIB causes the operation of the push button latches represented diagrammatically in this figure by the operating bar I20, its spring I2I opposing the magnet, with studs H4 and latches 91. In their outer or unoperated position the push button contact makers I09 are connected in series between their conductors I05, I09, by conductors I41 and the last contact III! is connected by a conductor I 40 through a thermostatic switch comprising a fixed contact I48 which engages a contact I50 mounted upon one end of a movable arm II having a pivot I55 at its other end, and controlled by a heating coil I52, the circuit continuing from the contact I5I through the coil I52 extending about the arm and through a conductor I53, thence through the winding of magnet 88 and conductor I54, spring contacts 88, 85, and conductor I44 to one of the main sources of supply I88. When any one of the push-buttons is depressed a contact is made with its corresponding xed contact I01 which leads to the remote control device which is thereupon operated for any desired purpose. In the case of a remote controlled instrument for playing a number of musical selections, the chosen selection is played.

When any push button is depressed, contact I08 first breaks the series connection between contacts I05 and I06, and then makes a connection between contacts I05 and I01, which completes the operative connection desired. Releasing the push button causes latch 81 to engage the stem 25 in a partially depressed position to illuminate the button, and at the same time allowing the contact maker I09 to be returned under the influence of its spring I II first to break connection with contacts I05 and I01, and then to re-establish series connection between the outer ends of contacts I05 and I08.

The remote controlled mechanism is represented as any one of the electro-magnets AI, A-2, etc., and assuming that switch S2 is depressed, the circuit through the magnet winding 88 and through the thermostatic heating device is completed through the series connections I41, and contacts I05, I06, until the contact maker I08 of switch S-2 is reached, which thereupon completes a circuit to its fixed contact I01, and thence through conductor C2, to magnet winding A2, which thereupon operates any remote device controlled thereby as presented by O2, the circuit then continuing through the common return con ductor I31 to the conductor I48 and thence through switch I42 to the other current supply main I43.

The circuit closed by any one of the push buttons is intended only to be a momentary or energizing contact which operates the magnet 88 to withdraw its armature and pawl extension 89 in a position to move the escape wheel 82 one step in the restoring direction. As soon as the circuit is broken by the return of the push button, the remote control operating circuit has been set up and that operation will continue until it is completed and breaking the circuit through magnet winding 88 causes the escape wheel to be moved one step in a return direction by its spring 83. If it should happen that the push button switch is held inwardly in closing connection with its contact I01, in an attempt to obtain a repetition of the same remote controlled action or operation, then the thermostatic heating coil I52 becomes heated to such an extent that the arm I5I is deflected about itsv pivoting point I55 at one end thereof, which operates the contacts I48 and I50 at the other end, breaking the circuit through the magnet 88, and thereupon causing the return movement of the escape wheel 82. This deteats the attempted repetition or continuation of the remote controlling circuit. After a predetermined time the cooling of the coil I52 connects the contacts I50 and I48, and the push buttons may be operated as desired.

An operator may insert any desired number of coins, producing a corresponding number of steps of the escape wheel for any number of push button operations. but when this predetermined number of push button selections has been made in the proper manner the escape wheel is returned until its contact pin 81 engages the spring finger 85 separating it from the contact 88 and thereby breaking the circuit connection through the magnet I I6, thereby releasing all of the locking latches 81 and allowing the push buttons to return to their normal outer position under the influence of their springs, as heretofore explained.

To illuminate the transparent portions of the push buttons, the electric lamps 21 may be supplied with current through supply mains I58 extending from a transformer 8| which is connected by conductors I58 and I58 to the other circuit supply mains for the system.

Thus, the controller provides means for individual selection of any number of remote operations, according to the denominations of the coins inserted for that purpose; provision is made for rejecting spurious coins; the controller prevents the selection of more than one operating circuit at the same time; and means is provided for preventing the fraudulent operation of any of the selected circuits.

This application is a division of my application Serial No. 182,708, filed December 31, 1937, now Patent No. 2,331,590.
